In the office, Baek Jina, hysterical and desperate, vehemently protested her innocence regarding the drug accusations. Beside her, the chairman spoke in a calm, almost clinical tone, insisting she adhere strictly to the established rules and procedures. Baek Jina's heart sank into a whirlpool of helplessness and confusion upon hearing his words.
Meanwhile, Min Ryul-hee was busy spreading the rumors over the phone, believing that the more people who learned of Baek Jina's supposed drug use, the better. Her conversation was abruptly interrupted by Jin Hae-in in the classroom hallway. Jin Hae-in, with a glimmer of defiance in her eyes, confessed to planting the drugs in Baek Jina's cabinet as per her instructions, ensuring Baek Jina's shame would be public knowledge. She then demanded Min Ryul-hee delete the incriminating video, but Min Ryul-hee, feigning ignorance, coolly refused, inflaming Jin Hae-in's anger. In a fit of rage, Jin Hae-in texted Jin Hye-in, threatening dire consequences unless she arrived promptly.
As Kim Hye-in hurried to the scene, she stumbled upon an unexpected sight in an empty classroom: Min Yool-hee and Cha Jin-wook locked in an intimate embrace. The sight of Cha Jin-wook betraying Baek Jin-na left Kim Hye-in reeling in shock. Just as she prepared to intervene, her phone buzzed again, urging her to depart swiftly. On the brink of their lips touching, Cha Jin-wook paused, querying Baek Jin-na's guilt regarding the drugs. Min Yool-hee, confident and cunning, affirmed the accusation, citing Baek Jin-na's stepmother's confession as undeniable proof. She seized the moment to pledge her unwavering loyalty to Cha Jin-wook and her ambition to become a part of Cha Se Pharmaceutical.
Kim Hye-in eventually found Kim Hae-in in an abandoned warehouse, where she demanded Kim Hae-in expose Min Yoo-hee's role in pushing her off the building. Though Kim Hae-in was aware of Kim Hye-in possessing Min Yoo-hee's necklace, she was unaware that Kim Hye-in had already given it to Baek Jina as part of a deal. Kim Hye-in revealed to Kim Hae-in the illusion of Diamond Six's power, peeling back layers of hypocrisy and deceit, including the revelation that Seo Do-yeon's departure was yet another facet of the organization's dark underbelly.
The mention of "Seo Do-yeon" ignited a fiery spark in Kim Hae-in's fragile psyche. She lunged at Kim Hye-in with crazy fury, choking the life out of her as she screamed accusations of betrayal. Kim Hye-in's face turned crimson under the suffocating grip, but with a final surge of strength, she pushed Kim Hae-in away, vowing to expose Min Yoo-hee's crimes to the chairman with the necklace as evidence. Kim Hae-in, in her mad joy, finally saw a glimmer of hope in escaping Min Yoo-hee's sinister clutches.
Bai Jina's father abruptly switched off the television and instructed her secretary to sever all ties and expedite their departure from the country. Bai Jina, disbelieving and protesting her innocence of drug use, faced a stone-walled silence from her father, who cited the company's board's intolerance for an addicted heir. As the elevator doors slid open, a throng of reporters eager for news on Hanming Group's next leader awaited anxiously outside, their camera flashes piercing Bai Jina's eyes like darts. Her secretary, tasked with negotiating a way through the media scrum, ushered her out a rear exit.
Left alone in the desolate office, Bai Jina felt an overwhelming sense of isolation and confusion. To her astonishment, she discovered her bank accounts frozen. Scanning her sparse contacts, she wandered the streets alone until she found herself at Kim Hye-in's doorstep. Kim's father greeted her warmly, offering her a comforting embrace of familial warmth that had always eluded her.
Realizing Baek Jina hadn't eaten, Kim Hye-in dashed out to buy instant noodles, leaving her friend behind. Just as Kim disappeared into the night, a shadowy figure emerged from the darkness, clutching a hammer with sinister intent. It was none other than the campus bully who had haunted Bai Jina's past. Fortunately, Lee Eun-rang appeared at the nick of time, tackling the assailant to the ground and threatening him with legal consequences, having documented his stalking behavior. With the man fleeing, Lee safely escorted Kim back home.
Kim Hye-in shared with Baek Jina the sight of Min Yoo-hee and Cha Jin-wook sharing a kiss, which Baek Jina dismissed with feigned indifference, her anger simmering beneath the surface. Elsewhere, Min Yoo-hee confided in her mother about her engagement to Cha Jin-wook, confident that her victory over Baek Jin Na was imminent.
Meanwhile, Cha Jin-wook tracked down Secretary Hong, who had substituted the medication at Baek Jin Na's house, only to find that Hong had cleverly recorded their illicit transaction. Cha Jin-wook confronted the teacher, offering a deal: halt the frame-up of Baek Jin Na for drug use, and he would ensure her continued role as the spouse of Han Ming Group.
Kim Hye-in and Lee Eun-rang identified Park Woo Jin as the man in black who had stolen Oh Si Eun's phone at the bar. Under the guise of meeting someone named Black Dog, they lured him to a specified location. While Kim Hye-in waited, her phone buzzed with a chilling message: a video of her undressing, sent by Min Yoo-hee.
